Abstract: Chaotic genetic algorithm (CGA) is presented as an optimization algorithm for sensorless adaptive optics system to compensate atmospheric wave aberration. Chaos search strategy is incorporated into standard genetic algorithm by the logistic function that possess convergent, bifurcating, and chaotic characteristics during evolution to control the convergence of genetic algorithm.Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effect of wavefront distortions.In the process of adaptive optics (AO) image, it usually takes post-processing for non-wavefront measurement data of the AO image, in order to get high-definition restoration images. Under the influence of atmospheric turbulence, it is difficult to determine the point spread function (PSF) of the AO image.

Adaptive optics technology has been employed in various systems to correct these aberrations and restore performance. This has required various departures from the traditional adaptive optics schemes that are used in astronomy.
Extremely Large Telescopes to very small and compact ones embedded in Multi Object Adaptive Optics systems, this paper aims at giving an overview of Deformable Mirror technology for Adaptive Optics and Astronomy. First the main drivers for the design of Deformable Mirrors are recalled, not only related to atmospheric aberration.
Voptica has developed the Visual Adaptive Optics (VAO) simulator, a disruptive innovation in eye testing, allowing patients to experience the effect of intraocular lenses or laser surgery on their vision before the actual operation, helping the patient and doctor to select their best solution and understand what their vision will be like post-surgery.
Adaptive optics (AO) is a supporting technology that enhances optical imaging by reducing the aberrations of an imaging beam. The basic concept was first proposed for ground-based telescopes with the aim of minimizing image blurring introduced by turbulences of the atmosphere.
Adaptive optics is a new technology which is being used now a days in ground based telescopes to remove atmospheric tremor and thus provide a clearer and brighter view of stars seen through ground based telescopes.
Adaptive Optics Adaptive optics is a technical development used for optical system performance improvement. It functions by reducing the result of wavefront distortions. Light from a faraway celestial subject gets distorted as it passes through earth's atmosphere, thus a telescope situated on earth's surface cannot form exact images.
The most active research topics for adaptive optics astronomy have been in solar system studies and in the observation of young stars and star forming regions. The benefit of adaptive optics most prominently exercised in these observations has been high resolution imagery, and the most common area of concern is the point spread function.
Feinleib’s idea was immediately classified and thereafter developed secretly by the defense community. In 1985, it was independently proposed in the open literature by Foy and Labeyrie 3.Ultimately, the defense work was declassified and the technique has come to be known as the laser-guide-star approach, which has vastly expanded the utility of adaptive optics and is an area of much research.
The basic principle of adaptive optics is depicted in the colored schematic. A beam of light is shined into the eye, and a small amount is reflected back out of the eye and into the optical system. Reflected light is split between a wavefront sensor (which measures the monochromatic aberrations) and the imaging device (can be thought of as a camera or a microscope).
Adaptive Optics Adaptive optics is a technological development used for optical system performance improvement. It works by reducing the effect of wavefront distortions. Light from a distant celestial object gets distorted as it passes through earth’s atmosphere, thus a telescope located on earth’s surface cannot form accurate images. It would take a telescope placed above Earth’s.
